-Symmetric Spin--Boson Model with a Continuous Bosonic Spectrum: Exceptional Points and Dynamics
Yong-Xin Zhang, Qing-Hu Chen
This work studies a -symmetric non-Hermitian spin--boson model, consisting of a non-Hermitian two-level system coupled to a continuous bosonic bath. The static proper…
Nonclassical Photon-Bundle Correlations in Quantum Rabi Models
Yong-Xin Zhang, Chen Wang, Qing-Hu Chen
We investigate nonclassical photon-bundle correlations in the quantum Rabi model and its extended cases, using the quantum dressed master equation. By tuning the light--matter coup…
Assessing the robustness of amortized simulation-based inference to transient noise in gravitational-wave ringdowns
Song-Tao Liu, Tian-Yang Sun, Yu-Xin Wang +4
Gravitational waves (GW) emitted by binary systems allow us to perform precision tests of general relativity in the strong field regime. Ringdown signals allow for probing black ho…
Factorized neural posterior estimation for rapid and reliable inference of parameterized post-Einsteinian deviation parameters in gravitational waves
Yong-Xin Zhang, Tian-Yang Sun, Chun-Yu Xiong +5
The direct detection of gravitational waves (GWs) by LIGO has strikingly confirmed general relativity (GR), but testing GR via GWs requires estimating parameterized post-Einsteinia…
Nonclassical correlations and quadrature squeezing of photons in anisotropic quantum Rabi-Stark model
Yong-Xin Zhang, Chen Wang, Qing-Hu Chen
This study investigates nonclassical effects of photons in the anisotropic quantum Rabi-Stark model by using a quantum dressed master equation. We analyze second- and higher-order…
